4 Wire 3 Phase Active and Reactive Din Rail Energy Meter ,
Electronic Watt-hour Meter
Product Description
Model YEM421MC three phase four wire electronic DIN rail active and
reactive integration energy meter is a kind of new style three
phase four wire active energy meter, it adopt micro-electronics
technique, and imported large scale integrate circuit, use advanced
technique of digital and SMT techniques, etc. The meter completely
accord with relevant technical requirements of class 1 three phase
active energy meter stipulated in international standard IEC
62053-21 and class 2 three phase reactive energy meter stipulated
in international standard IEC 62053-23. It can accurate and
directly measure 50Hz or 60Hz active and reactive energy
consumption from three phase four wire AC electricity net, it can
display total energy consumption by step motor type impulse
register. This meter has seven digits LCD displays shows active
energy. And there is a maintenance-free lithium battery in it, use
for displaying power cut reading. It has following features: good
reliability, small volume, light weight, specious nice appearance,
convenient installation, etc.

Competitive Advantage
1. 35mm standard DIN rail installation, complying with standard DIN
EN50022. Or front board installed (mounting holes center distance
63 mm), users can choose any one by themselves.
2. Ten pole width (Modulus 12.5mm), complying with standard
JB/T7121-1993.
3. 7 digits LCD display, 6+1 digits(999999. 1kWh),may select 5+2
digits display. (Please specified when ordering)
4. There is a maintenance-free lithium battery in it, use for
displaying power cut reading.
5. Standard configuration one port of active pulse output passive
and one port of reactive pulse output passive(polarity),The output
rate are 0.01, 0.1, 1, 10kWh or kvarh/Pulse. Users can choose any
one by themselves. May select one port of active pulse output
passive and one port of reactive pulse output passive
(nonpolarity). And contact with all kind of AMR system
conveniently,Complying with standard IEC 62053-31 and DIN 43864.
(Please specified when ordering)
6. Five LED instructions every power supply state and signal of
active energy impulse and reactive energy impulse.
7. Automatic detection the direction of the flow of load current.
And instructions by one LED.
8. Single direction three components measure three phase four wire
active and reactive energy consumption. It is nothing with
direction of the flow of load current. Complying with standard IEC
62053-21and IEC 62053-23.
9. Standard configuration type S wiring (Inlet from top, outlet
from bottom), directly connect operation, may select use CT
(Product Configuration code is LC) and PT&CT (Product
Configuration code is KC) for operation.
10. Standard configuration short terminals cover, may select
extension terminals cover, in order to protect to use safety.
(Product Configuration code is MF).
